Sackville believes the key to making healthy relationship decisions is to "really know yourself".

"And sure, there are women who want to go out and have no-strings sex or just date a lot of people and have fun, but you need to know if you're capable of doing that,” she says.

While dating can be "really fun", it's not all uncertainty and drama. Still, the author advises single women to keep a few things in mind.

"You need to be very good at screening people, you need to be very good at recognising red flags, you need to be really good at dealing with rejection because that's going to happen, a lot,” Sackville says.

"It doesn't mean you're unlovable or unworthy, it just means you don't resonate with that person."
